The "record have key_type, value_type, and .at method" suggestion would blindly 
exclude any map-related at() method, even if its semantics are different,

Do you think this could cause any issues? Is it fair to assume that other 
libraries will define it so that it needs to be excluded?
Worst case, we have false negatives. Or am I misunderstanding something?
